Update: End of week 12 of following conservative (no surgery) rehabilitation largely based on the 10 week program in the link in the previous post.
[The exercises starting in week 9 I was unable to do due to lack of equipment, but did best I could to do something rotational to replicate in some form]
Week 11: I ran 400m intervals at down to CV pace each day, starting at 4x increasing to 8x at end of week. I experienced some discomfort, always on the first 100-200m before core had been correctly engaged and everything firing correctly, but after that, nothing more than a sensation, slight discomfort. Post runs, a couple of days there was some aggravation/ inflammation to the point that I thought the next day may not be ok to run, but everything was fine, and progressing into the next week, things were fine. Between intervals I stuck with jump rope for 3'.
Week 12: Pretty much following a reduced volume version of Klaas Lok's EIM, using 800m, 400m, 200m at paces of approx tempo/threshold, CV, 1mile respectively, jogging same distance between reps (using jump rope as w/u). I'm working on the basis that as long as there is no pain, and as long there is no worsening/ aggravation from day to day then I will keep going. (This is basically a similar approach to the recommended rehab for achilles issues based on the Scandinavian research which worked for me). Symptoms have reduced further with nothing more than a twinge/ sensation at any time.
At this point, a full recovery looks fairly promising, but subject to continuing to do the work to strengthen/ correct imbalances of which the following exercises I believe to have been of fundamental importance - bulgarian split squats, slide to side lunges (similar to slideboard), lateral step ups, dead bugs, single leg bridges. I have not used any weights as the rehab program linked suggests (partly due to lack of access to equipment), and I have used a higher frequency, higher reps, fewer sets approach - basically, using bodyweight and a single set of 20 for one to three exercises for lower body daily, and the other stuff 4-5 days a week of 2 sets each of 20.
I hope this helps anyone considering surgery or not as at this point, I do believe that it may well be possible to avoid surgery through patiently working through such a program and I thank all those people who have given their input of their experiences of the horrific complications that they have experienced with surgery and the pointed towards trying to rehab first.
Additionally, I will note that the author of the program linked above has a page with regard to surgery in which he strongly recommends not using the mesh surgery, but going for the minimally invasive method developed in Germany if surgery cannot be avoided.
